installation tips

• Position the speed-control and capacitor where they are protected in the event of a crash and gives you easy
access to the connectors and buttons.
• Mount the speedo and capacitor using the supplied thick/black doubled-sided tape
• Make sure there is enough clearance between the speed-control, power-wires, antenna and receiver. Avoid
any direct contact between power components, the receiver or the antenna as this can cause interference. If
interference occurs, position the components at a different place in the model.
• The aerial should be run vertically up and away from the receiver. Avoid contact with any parts made of carbon
fibre or metal. If the aerial is too long, don't coil up the excess length. See also the instructions supplied with
your radio control system.
wires & installation
The SXX StockSpec comes supplied with flexible 3.3mm² silicone power-wires without connectors. Be very careful
with the correct wire sequence/colors since an incorrect connection may damage the speed-control! Avoid crea-
ting solder bridges on the solder-tabs and isolate all connections carefully.
Caution: Avoid soldering longer then 5sec per soldering joint when replacing the power wires on the speed-control
and motor to prevent possible damage due to overheating of the components!
• Connect the speed-control to the receiver (position: Channel 2
• Blue power-wire  Speedo MOT.A to motor „A"
• Yellow power-wire  Speedo MOT.B to motor „B"
• Orange power-wire  Speedo MOT.C to motor „C"
• Connect the hall sensor cable to the speed-control (underneath the solder-tabs) and the motor.

• Doublecheck all connections before connecting the speed-control to a battery.
CAUTION: If battery is connected with reversed polarity it will destroy your speed-control!
• Red power-wire  Speedo BAT+ to battery „Plus"
• Black power-wire  Speedo BAT- to battery „Minus"
• The speed-control is now ready to be set-up (see section 5).

Receiver Connecting Wire:
The SXX StockSpec
is equipped with an LRP Multicon receiver wire. As
supplied, it will easily fit in all ordinary receivers.
Make sure you connect it to receiver with correct
polarity and use channel 2.
Sensor Connector:
located underneath the solder
tabs. The bi-directional multipole sensor wire con-
nects the speed-control and the motor. Always use
the sensor wire and do not alter or modify this cable!
There are replaceable/optional hall sensor wires
available, please refer to complete line-up at „Spare-
& Optional-Parts".
Power Wires:
For maximum performance, flexible
silicone power wires without any connectors are
used. The unique splitted solder-tabs allow easy and
convenient replacement of the power wires. Never-
theless some soldering skills are required. Avoid sol-
dering longer then 5sec per soldering joint to prevent
possible damage to the speed-control due to overhea-
ting of the components! There are replacement power
wires available, please refer to complete line-up at
„Spare- & Optional-Parts".
Heatsink:
To achieve best perfomance even under
extreme conditions, the heatsink has been directly
mounted to the speed-control. This ensures the best
possible heat transfer away from the speed-control.
Caution: Never attempt to remove the heatsink or
your SXX StockSpec may get damaged if you try to do
this. The heatsink is an integral part, glued to the fet's
and therefore cannot be removed.

radio- / speed-control setup

In setup mode the SXX StockSpec stores every step (e.g. learning your radios neutral and endpoints) by pressing
the SET button. All the settings will be stored in the memory even if it will be disconnected from the battery.
TRANSMITTER SETTINGS: Setup the following basic functions on your transmitter (if available):
Description other names in radio
Throttle Travel High ATV, EPA
Brake Travel Low ATV, EPA, ATL
Throttle Exponential EXP, EXPO
Neutral Trim SUB Trim
Servo Reverse Throttle Reverse
If your transmitter doesn't offer any of above functions, it's already in „basic setup" mode.
• Ensure that the speed-control is not connected to the drive battery and is switched off.
• Remove motor pinion or ensure that the wheels of the model are free to rotate.
• Switch the transmitter on and set the transmitter throttle stick to neutral.
• Connect the speed-control to the battery and switch the unit on.
• Hold the SET button pressed for at least 3sec.
 You entered setup mode and the SET LED flashes blue (it will flash until the setup is completed).
• Leave transmitter in neutral position and press the SET button once.
 Neutral setting is stored , MODE LED flashes yellow and the motor beeps.
• Hold full throttle on transmitter and press the SET button once.
 Full-throttle setting is stored, MODE LED flashes red.
• Hold full brake on transmitter and press the SET button once.
 Brake setting is stored, LED's glow red (MODE) and blue (SET).
• This completes the setup procedure and your SXX StockSpec is ready to use.
• If you make a mistake during the setup procedure, don't worry: Disconnect the battery for about 10sec and start
again from the first step.
• At the end of each run switch of the car, and then switch off the transmitter.
• At the start of each run switch on the transmitter first, then switch on the car.
• For storage of the car, disconnect the drive battery at any time!
Team advise: A good starting point for the brake setting on your radio is 80% for all classes. Make sure you do the
radio-setup with all settings on the radio on 100% and then decrease brake strength to 80%!
CHECKING THE FUNCTIONS: Check the LED's when moving your throttle stick and you will see if everything is
setup correctly.
